The fichedule referred to in thesolotten iatent and making purl: of thesame.

To all whom it may concern Be it known that I, WELIAM G. DEAN, ofBrooklyn, in the county of Kings and State of New York, have inventedand made a new and useful Improvement in Preparing Flour, and thefollowing is declared to be a correct description thereof.

Wheat and other kinds of flour have been used in the arts andmanufactures for the purpose of giving color to different substances,such as confectionery and mustard, in the latter instance imparting tothe brownish mustard the brilliant yellow generally preferred.

.Elour for such purposes has been colored by turmeric, and the methodpursued has been to mix ground turmeric with flour, then to regrind themass, to produce an intimate union, and then the mass is exposed to theatmosphere, which frequently requires several days for the color to bedeveloped, and afterward the color changes from a light yellow to adarker yellow.

lnthis manner much more turmeric is required-than in my process, and thecolor is not permanent, but grows darker.

I have discovered that the action of heat causes the turmeric to impartcolor rapidly to flour, and enables me to use a very small proportion ofturmeric and obtain a permanent color.

I mix about three pounds of grouud'turmeric with about one hundredpounds of flour, or in about that proportion, and place themjn asuitable vessel where the mass can be stirred or agitated thoroughly,and at the same time submitted to .a temperature of 200- Witnesses:
